Masodas Ransomware

Once cybercriminals find a winning formula, they keep getting back to it again and again. This is what has happened with Masodas Ransomware, a malicious infection that was created for the sole purpose of making money for cyber attackers. This infection is not unique. On the contrary, it is a variant of a well-known threat, STOP Ransomware, and there are plenty of other variants too. A few of them include Mogranos Ransomware, Darus Ransomware, Kiratos Ransomware, or Guvara Ransomware. All of these infections work the same, and as soon as they manage to slither in, they encrypt files. After that, ransom notes are created to push victims into paying money for alleged decryption tools. Without a doubt, this malware is exceptionally dangerous, but not all is lost. It appears that a free decryptor was created by malware fighters. Hopefully, you can restore your files soon, but even if you succeed, you should not wait to remove Masodas Ransomware. The sooner this threat is gone – the better.

It is easy to identify Masodas Ransomware because when it slithers in and encrypts files, the “.masodas” extension is added to the names of the files. What is the purpose of this extension? It serves no other purpose than to mark the corrupted files. You can easily remove this extension, but what would be the point of doing that? Also, since a decryptor appears to exist, you should not try to manipulate or change the corrupted files in any way. Unfortunately, victims usually panic, and they do not even take a moment to breathe and research the infection. This leads them to follow the demands of the malicious attackers. The demands are introduced to them using a file named “_readme.txt,” which should be created in the local drive (C:\). According to the message, a decryption tool and a unique decryption key are what you need to have the files decrypted. To obtain it, you need to pay for it, and to get more information about the payment, you have to contact the cybercriminals by sending them a message to or If you do this, the attackers could flood your inbox with spam, phishing emails, and emails containing malware. So, if you decide to send a message, do so from a separate email account that you could delete later on. That being said, we do not believe that a decryptor would be sent to you after payment, and so contacting the attackers is not recommended.

As you know, Masodas Ransomware is not the only infection in the world. The STOP Ransomware family is not the only family of ransomware either. In fact, there are thousands of file-encrypting threats out in the wild, and if your system is not prepared to fight them off, any one of them could invade your system next. The attackers know all of the secret pathways that can lead them straight into your operating system, and they know all of the tricks that can help them get there. We cannot say how exactly Masodas Ransomware got into your Windows operating system, but if we had to guess, we would look into spam emails and RDP vulnerabilities, as these are used most often. Without a doubt, it is also important to inspect the operating system for additional threats that could have slithered in along with the ransomware or that could have been instrumental in executing this threat in the first place.

In conclusion, if your operating system has been attacked by Masodas Ransomware, it is pretty obvious that your operating system lacks reliable protection. What should you do about it? Of course, you want to strengthen protection, and you can do it using anti-malware software. It will automatically delete Masodas Ransomware and any other threats that might be active. At the same time, it will keep your entire system protected. Unfortunately, anti-malware software cannot restore files. It is believed that a tool called STOPDecrypter should provide victims with free decryption services, but do not install anything carelessly. The last thing you need is to install an impersonator program that disguises malware. Ultimately, we hope that you can restore your files and delete the infection, but do not forget that there are plenty of other infections that could harm your files and that free decryptors do not work on all of them. To secure files, create backups online or on external drives.
